function span(v, c)
A = [];
n = length(A);
for i=1:n
u=c{i};
u= u';
A = [A u(:)];
end
v= v';
v=v(:);
if rank(A) == rank([A v])
disp('Given vector is in the span.')
else
disp('Given vector is not in the span.')
end
All functions in a script must be closed with an 'end'.
I don't understand this response...thanks

You must have included this in your script. This is not all of your code.
The direct solution for this is to add an "end" line at the end, to mark the "end" of the function span(v, c)

If you're writing a function inside a function file and any function in your function file ends with an end then every function in your function file must end with an end.
If you're writing a function inside a script file that function must end with an end.

The existing end on the last line of your code is the end matching the if statement. You need an additional end statement matching up to the function line.
